Fig. 2 is the structural representation of frock closed cavity among Fig. 1;
Fig. 3 is control circuit figure of the present invention.
The specific embodiment
As shown in Figure 1.Hydraulic machine 1 and patrix 13 thereof, counterdie 14 are identical with existing hydraulic press, are prior art.Frock closed cavity 7 is contained on the counterdie 14.Gas cylinder 9, magnetic valve 6, vacuum tank 10, two-position three-way valve 8, vavuum pump 5 and be connected tracheae 15 and constitute aerating devices, vacuum tank 10 is provided with electro connecting pressure gauge 12.PLC control system 2, two limit switches 4, baroceptor 3, two-position three-way valves 8 constitute 1 operation of control hydraulic machines and vacuumize and fill the aerating device of detection gas for frock closed cavity 7.Two limit switches 4 are located at respectively on the upper and lower extreme position that hydraulic machine 1 patrix 13 moves.Baroceptor 3 is contained in and being connected on the tracheae 15 that frock closed cavity 7 communicates.Detecting gas and select helium for use, also can be other nontoxic gas.
As shown in Figure 2.The middle part of frock closed cavity 7 is provided with recessed column type closed cavity 17, and Si Jiaochu is provided with screw-socket 16.Connecting tracheae 15 communicates with closed cavity 17.
Control circuit as shown in Figure 3.The model of central processor equipment PLC is FXIS-30MR.PLC accepts the input signal instruction of input signal circuit, is handled by PLC according to computer programming and sends fill order, is realized by output circuit.
The input signal circuit is controlled KA1, lower limit control KAO1, start control button SB1, conversion and control button SA2, remote control signal QFO, overload protecting circuit FRO, air pressure sensing signal KQA, hydraulic press interlock protection circuit FR1 and PLC by upper limit and is formed.
The output signal circuit comprises: the permission that is made of relay K A4, written instructions lamp HL4 and PLC moves circuit; The vavuum pump that is made of A.C. contactor KM1, stop button SB2, circuit breaker Q F1, electrothermal relay FRO and PLC moves circuit; The hydraulic press that is made of auxiliary reclay KA2 and PLC moves circuit; The three-way magnetic valve control circuit that constitutes by auxiliary reclay KA3, indicator lamp HL5 and PLC; The integrated alarm circuit that constitutes by auxiliary reclay KA5 and PLC.
Give PLC by baroceptor KQA input signal, limit switch SQ2 action situation signal feedback, finish the input instruction, give KA2 by PLC output point output order again, control hydraulic press motor, vaccum pump motor running according to the PLC input point.Upper limit position switch SQ1 closes, baroceptor 3 detects air pressure automatically, hydraulic pressure master motor is just changeing descending, closes to lower position switch SQ2 to stop, and two-position three-way valve 8 opens to the helium injection gaseity simultaneously, constant voltage pressure is to extremely setting value, pressing generator counterdie rises, and finishes the action of frock closed cavity, after machining, the counter-rotating of hydraulic pressure master motor is up, close to upper limit position switch SQ1 and to stop, vacuum pumping pump work detects air pressure to setting pressure to baroceptor 3, and vavuum pump is out of service.Chain by auxiliary reclay at KA3 and hydraulic press electric control system, coordinate to finish the work.
